WATER-GATE.

SPECIFICATION forming part of Letters Patent No. 330,800, dated November 17, 1885.

Application filed March 21, 1885.

To all whom it may concern:

Be it known that I, RICHARD PATTEE, a citizen of the United States, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Water-Gates, of which the following is a specification.

This invention relates to improvements in water-gates, the object being to provide an improved revolving plug-gate, the plug of which has attached thereto loosely valves which have a motion thereon by turning the plug in the direction of the water-way to close the passage through the gate.

In the drawings forming part of this speciiication, Figure 1 is a top plan View (with the head removed) of a water-gate embodying my invention. Fig. 2 is a longitudinal section on line as m, Fig. 1. Fig. 3 is a perspective view of detached parts, partly in section.

In the drawings, a is the barrel of the gate having the usual socket-nozzles, B B, on 0pposite sides thereof. D D are heads which are secured by screw-bolts or other suitable means on each end of the barrel a after the plug 1; has been inserted therein. The lower head, D, has a central step, 2, to receive one plugbearing stud, y, and the upper head, D, has a hole through its center, through which passes the upper bearing-stud of the plug 3 and an ordinary stuffing-box is made in head D, having the packing-nut n, whereby any leakage around the stud y is prevented. The end of the last-named stud is squared to provide for any convenient attachment thereto for turning the plug. Theheads D D are each made with two projections or pins, '0, on their inner faces, as shown. The interior of the barrel a, except directly around the inner ends of the nozzles B at w, is eithe nleft in the condition in which it is cast on ordinarily finished, as it needs no grinding, as is the case with ordinary plug-valves; but at the points 10 within the barrel a slightly-raised collar is provided, for the purpose hereinafter set forth, said collars being properly faced andfinished. The plug, or more properly the gate-wheel b, as aforesaid, has the studs 3/ on either end, for the Serial No. 159,631. (No model.)

purpose described, and on opposite sides thereof is formed a wide groove, m, in the direction of the length of the wheel. The diameter of wheel I) is such that,when placed in the barrel, it rotates freely between the collars w, the latter constituting gate-seats, as hereinafter set forth.

A segmental gate, 0, is loosely fitted into the groove m on each side of the wheel I) in the position shown, said gate having on each end a cam-flange, e, projecting over each end of said wheel toward its center. The edge of the flange e is eccentric to the curve of the outer surface of the gate 0, as shown. When the gates 0 lie close against the sides of the wheel I), their outer surfaces are about flush with the surface of the wheel each side of the groove m. 7

Figs. 1 and 2 show the relative positions of the projections v on the heads D D, and the gate-wheel and gates, together with the camfianges e, when the passage through the gate is open. In Fig. lthe projections to are shown in section as though out off from the head when it was removed and left in the positions over the end of the wheelb which they occupy when the head is on.

As shown in Fig. 1, the gates a stand on opposite sides of the passage-way through the water-gate when the latter is open, and in shutting the latter the wheel I) is turned to the right in Fig. 1, thereby carrying the narrow ends of the cam'flanges 6 against the sides of the projections 12, when wheel I) is turned, thereby forcing the curved outer face of the gates 0 against the collars w, around the nozzle openings on the barrel, and tightly shutting said openings.

The dotted lines in Fig. 1 on the end of the wheel b show the positions of the cams e just after engaging with the projections 2;.

When the gate is fully shut and the gates 0 come to a bearing against the collars w in the barrel, their opposite bearing-points are two of projections 1), one at each end, upon which they are free to oscillate more or less, and adjust themselves to a proper bearing against the face of the collars w.

What I claim as my invention isgagement with said cam-flanges on the gates, The gatewheel b, having the grooves m and the barrel (1, all combined and operating therein to receive the gates, and having a substantially as set forth pivot-connection with both heads of the gate, RICHARD PATTEE. 5 the gates c, of segmental form, having on each Witnesses:

end thereof a cam-flange, e, the heads D D, H. A. GHAPIN,

each having the two pins 22 thereon, for en- J. D. GARFIELD.
